| Weld Schedule | A set of pre-defined, qualified parameters for welding or deposition (including current, voltage, speed, and gas) that ensures a repeatable and structurally sound result. |
| Wire Arc Additive Manufacturing (WAAM) | An alternative DED process that uses an electric arc (like a welding torch) instead of a laser as the energy source to melt the wire. WAAM is typically faster but produces parts with lower resolution and a rougher surface finish than LMD-W. |
| Wire-Laser Metal Deposition (WLM-DED or LMD-W) | Meltio’s patented metal additive manufacturing process, a type of Directed Energy Deposition (DED) , that uses a focused laser to melt a continuous feed of welding wire into a melt pool to create or repair fully dense metal parts. |
| Zero Material Waste | A major cost and sustainability advantage where 100% of the wire feedstock is deposited into the final part. This contrasts with powder-based methods that often leave unused or contaminated material. |
